Here's my view on HobbyKing.
Stay away from the Orange Radio, DSM2 is outdated and there is no warranty support like you get with Spektrum.
The HK 450 GT CCPM 3D Full Alloy is a decent kit.
It costs around £37.
I have fitted the following genuine Align parts to get a helicopter that is as good as an Align Trex 450 GT V2.
- Main shaft
- Main gear
- Tail drive gear
- Tail pitch slider
- Canopy
I have also fitted a RJX flybarless head and Tarot ZYX.
It flies flawlessly and looks good too.
The HK 250 isn't great, and I find it hard to recommend, but the HK 250 flybarless head is superb for $20.
You do have to fit genuine Align radius arms and feathering shaft however.
If you are looking for a 450 Pro clone, go for the Tarot one instead, it's almost as good as the genuine Align.
